APPARATUS FOR CONDENSATING STEAM.

SEECIFIOATION forming part of Letters Patent No. 745,513, dated. December 1, 1903.

Application filed August 21, W03. Serial No. 170,317. (No model.) d

To all whom it may concern:

Be it known that [,WILHELM J noon Nuss, engineer, a subject of the King of Prussia, German Emperor, and a resident of Cologne- Lindenthal, Prussia, Germany, have invented certain new and useful Improvements in Apparatus for Oondensating Steam and Purifying Water, of which the following is a specification y My invention has for its object to provide for the suction of the steam by a water-injector and for mixing the stream of steam and water with an air-current, which in conjunction with the cool water condenses the steam, makes the water iron tree, and raises its temperature so as to be suitable for feeding purposes. In combination withsuch means are provided several concentric precipitatingtubes and a common slime-pit, so that the water, which for the purpose of softening is mixed with lime and soda, descends and ascends several times before it rises to a filter, while the heavier impurities of the water precipitated in the middle tube catch and depress the lighter impurities precipitated in the other tube down into the common slimepit.

These improvements are shown in the accompanying drawings, presenting a .verti- 3o cally-sectional view of the new apparatus.

The apparatus comprises a vertical cylinder 0., which is divided by partitions b and 0 into three compartments. The upper compartment is by a vertical partition 11 divided into two compartments e f, which serve as tanks for solutions of lime and soda. In the middle of these compartments is provided a fiat hopper g and a fiat conical screen h. The undermost compartment contains two verti- 0 cal concentric pipes t' it, open at both ends. The outer pipe is, of larger diameter than the inner pipe 0 has its ends standing in lower levels than the respective ends of the inner pipe. A mantle Z, which is cylindrical at its 5 upper part and conical at its under part, surrounds said pipes and is connected to an annular filter m.

n represents the steam-pipe, the fore end of which is bent down into the upper end of a pipe 0, having the form of two truncated cones having their small bases common or coincident. The upper cone is connected by pipe a an injector (1 extends,

cooks for simultaneously supplying the compartments e and f with fresh water. The solution of soda from the compartmentffiows through cock to and pipe 1) into the middle one of the compartments or the water-heater w. A funnel a: has connection with the upper part of the undermost compartment above its water-level by openings 3 z designates the slimedischarge cock, and a the discharge-pipe for the purified water. he operation of the apparatus is as follows: By the water-stream of the injector q the steam passing the steam-pipe n is sucked and forced with the water into the cones o. 7

This mixture of steam and water on passing the cones forces along with it a current of air which enters the mouth of the upper cone o under the effect of the draft exerted by the funnel 00. The mixture of steam, water,

and air on passing the cones 0 is mingled with lime-water, which flows over from the compartmen'te through pipe 19 and is dropped into the middle of the compartments w,where it spreads over the screen It and the hopper g and is furthermore mingled with solution of soda supplied from the compartment f. The water-stream in conjunction with the aircurrent efiects acondensation of the steam, while the cool water is brought to a high temperature suitable for use as feed-water. By the oxygen of the air in the mixture the iron of the water is oxidated, and so the water rendered free of iron, while by the addition of lime and soda to the water its carbonates and magnesia compounds are precipitated'. By spreading the water over the screen 72. and afterward contracting it in the hopperg on simultaneously adding to it the chemical ingredients an intimate mingling of the water with these ingredients is eflfected. From the hopper g the water drops into the pipe 1', while the air forced along with the stream of steam and water is sucked by the funnel a: and removed. The water descends and ascends through the pipes 'ik and mantle Z in a zigzag course, (shown by the arrows,) until it rises to the filter m, where it is delivered in a purified state through dischargepipe 2. All the impurities contained in the water drop into and are caught in one common slime-pit provided with the cock 2;. By the shown arrangement of the concentric tubes 42 70 an efficient purifying of the water is attained, because the lighter impurities which percipitate in the pipe is are caught and pressed down in the slime-pit by the heavier impurities precipitating in the pipe 2'. The descending and ascending movements of the water in the pipes "i k are caused by the different specific Weights of the circulating water columns.

What I claim as my invention, and desire to secure by Letters Patent, is

1; In an apparatus for condensating steam and purifying water, the combination of a steam-pipe which empties into a pipe made up of two truncated cones the small bases of which are coincident; a water-injector which extends into said steam-pipe; said pipe made up of two truncated cones the small bases of which are coincident;

a pipe which connects the last-named pipe with a lime and water containing compartment; and said compartment.

2. In an apparatus for condensating steam and purifying water the combination with an injector for cool water, of a steam-pipe the forward end of which incloses this injector and is bent down into the upper mouth of a pipe having the form of two truncated cones with one commonsmall basis, a pipe connecting these cones with a lime and water containing compartment, two or more vertical concentric tubes having their open ends in different levels for descending and ascending the circulating water and for precipitating the impurities before the water rises to a filter and a slime-pit common to all precipitating-tubes.

In witness whereof I have hereunto set my hand in presence of two witnesses.

WILHELM JACOB NUSS.
